My partner and I have have always had issues riding together because my comfortable cadence is about 20% faster than hers. We have tried in-phase and out-of-phase cranks, and it doesn't seem to improve the situation.
I am toying with the idea of swapping out her 36-too timing gear for a 42, wile leaving mine a 36, the idea that I can spin and she can troll along. Neither of us are heavy mashers and have a relatively smooth stroke. Has anyone tried this??
